Web Application Firewall (WAF) is a dedicated firewall that filters, monitors, and blocks HTTP traffic to and from web application. By inspecting the traffic, WAF protects the network contents from attacks originated from web application vulnerabilities.
As a key component of Alibaba Cloud Security, WAF applies to most common web attacks, such as SQL injections, XSS, web shell, Trojan, and so on. Besides, it improves the website performance through HTTP or HTTPS floods mitigation, and bad bot protection. Meanwhile, through WAF, customized security policies are available for various scenarios.
Compared with traditional hardware devices, Alibaba Cloud WAF can be set up to protect your web service within 10 minutes, with no complicated hardware deployment or tedious settings of appliances such as routers and switches.
